Objective To assess the potential role of disulfidptosis-related genes (DRGs) in pan-cancer on prognosis and immunity on the basis of bioinformatics approaches. Methods Pan-cancer RNA-seq data, mutation profiles, clinical information, TMB, MSI, stemness scores, and tumor and immune microenvironment data contained in TCGA and various open-source online databases, and multi-group R-language algorithms were used for comprehensive analysis. The expression levels of DRGs at the cellular level were experimentally validated using qPCR. Results LRPPRC, NCKAP1, NDUFS1, and NUBPL had a better prognosis in renal clear cell carcinoma (P<0.001), whereas SLC7A11, NCKAP1, and SLC3A2 had a worse prognosis in hepatocellular carcinoma (P<0.001). TME analysis showed that LRPPRC was negatively correlated with immune cells, stromal cells, and estimated scores in all tumor types. TMB analysis revealed the potential research value of DRGs for PD-1/PD-L1 therapy in pan-cancer. Drug sensitivity analysis showed that SLC7A11 (r=0.454), SLC3A2 (r=0.366), and NCKAP1 (r=0.455) were significantly associated with Kahalide F (P<0.01). Experimental validation demonstrated the overall higher expression levels of GYS1 and NCKAP1 than normal cells in lung adenocarcinoma, colon adenocarcinoma, esophageal squamous carcinoma, and hepatocellular carcinoma (P<0.05). Conclusion Pan-cancer analysis of DRGs indicates that DRGs may serve as important biomarkers for the diagnosis and prognosis of renal clear-cell carcinoma, lung adenocarcinoma, and hepatocellular carcinoma.

OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

OBJECTIVE To explore the effects of the water extract of Morinda officinalis on the expressions of sex hormones and receptors in bisphenol A （BPA）-contaminated mice. METHODS Totally 60 male Kunming mice were randomly divided into control group， model group， and low-dose， medium-dose and high-dose groups of M. officinalis water extract （20， 40， 60 mg/kg）， with 12 mice in each group. The model group and M. officinalis water extract groups were given BPA intragastrically [50 mg/（kg·d）， once a day， for 4 consecutive weeks] to establish the BPA-contamination model of mice. After modeling， each drug group was gavaged with the corresponding drug solution， once a day， for 4 consecutive weeks. After the last medication， the body weight and testicular weight of the mice in each group were weighed， the histopathological changes in the testis were observed， and the serum sex hormones [luteinizing hormone （LH）， follicle-stimulating hormone （FSH）] contents and the mRNA and protein expressions of LH receptor （LHR） and FSH receptor （FSHR） in the testicular tissues were detected. RESULTS Compared with the control group， the testicular tissues of mice in the model group had structural degeneration， loose connections between spermatogenic cells and Sertoli cells， obvious lacunae and reduced number of spermatogenic cells； the mRNA and protein expressions of LHR and FSHR in testicular tissues were significantly down-regulated （P＜0.01）， but there were no significant changes in their body weights， testicular weights， and serum contents of LH and FSH （P＞0.05）. Compared with the model group， the histopathological changes of testicular tissues of mice in each dose group of M. officinalis water extract were improved to different degrees， and the mRNA and protein expressions of LHR and FSHR in testicular tissues were up-regulated to different degrees （P＜0.05 or P＜ 0.01）， and some indicator levels were similar to those of the control group （P＞0.05）. However， there were no significant changes in their body weights， testicular weights， and serum contents of LH and FSH （P＞0.05）. CONCLUSIONS The water extract of M. officinalis has a certain improvement effect on testicular injury in BPA-contaminated mice， which might be related to its increase in the mRNA and protein expressions of LHR and FSHR.

OBJECTIVE To explore the safety， effectiveness， and cost-effectiveness of elderly patients with sarcopenia receiving Shenling baizhu powder combined with nutrition and exercise intervention， providing a reference for rational clinical drug use. METHODS A total of 237 elderly sarcopenia patients were randomly assigned to an observation group （118 cases） and a control group （119 cases）. Both groups of patients received nutrition and exercise intervention； the observation group added Shenling baizhu powder （6 g each time， three times daily） on this basis. The safety， effectiveness， and cost-effectiveness of the two plans were compared after 3 months. RESULTS Both groups of patients completed the follow-up. Before intervention， no significant difference was observed in skeletal muscle index （SMI）， grip strength， and 6-minute walk test （6MWT） speed between the two groups （P＞0.05）. After intervention， the grip strength of the patients in the observation group was significantly greater than that of the control group （25.05 kg vs. 23.18 kg， P＜0.01）； the treatment response rate of sarcopenia， SMI， and 6MWT speed were higher than those of the control group， butthe differences were not statistically significant （P＞0.05）. The adverse reaction/event rate of the patients in the observation group was lower than that of the control group （14.41% vs. 16.81%， P＝0.611）， but the difference was not statistically significant. Compared with the control group’s plan， the cost of the observation group’s plan was higher （981.25 yuan vs. 913.94 yuan）， and the effect was better （effectiveness rate： 0.618 6 vs. 0.563 0）， with an incremental cost-effectiveness ratio of 1 210.61 yuan. The results of the sensitivity analysis were consistent with the cost-effectiveness analysis results. CONCLUSION Elderly patients with sarcopenia who receive Shenling baizhu powder combined with nutrition and exercise intervention can significantly strengthen grip strength without increasing the incidence of adverse reactions/events. Compared with the control group plan， the observation group needs to spend an additional 1 210.61 yuan for each additional effective patient with sarcopenia.

Objective The objective of this study was to explore the values of hsa-let-7b-5p in the clinical diagnosis and targeted therapy of non-small cell lung cancer(NSCLC).Methods Thirteen pairs of NSCLC tissues and their adjacent tissues with the same pathological type in Harbin Medical University Cancer Hospital from September to October 2020 were collected,and differen-tially expressed miRNAs were obtained by RNA-Seq,and the expression of candidate miRNAs were verified in NSCLC tissues and cells through qRT-PCR.The effects of miRNAs on the proliferation,migration and invasion ability of NSCLC were verified by CCK-8 assay,clone formation assay,scratch assay and Transwell assay.Target genes were predicted using MiRDB,TarBase and ENCORI da-tabases,and gene enrichment analysis was performed using FunRich tool.Results Compared with adjacent tissues and human bron-chial epithelial cells(HBE),hsa-let-7b-5p was downregulated in NSCLC tissues and cell lines(A549 cells,H1299 cells,H358 cells and H460 cells)(P<0.05).The high expression of hsa-let-7b-5p inhibited the proliferation,migration and invasion ability of NSCLC(P<0.01).The results of target genes and enrichment analysis showed that among 378 target genes and related genes of hsa-let-7b-5p,147 genes were negatively correlated with the expression of hsa-let-7b-5p(P<0.05).Conclusion Hsa-let-7b-5phas inhibitory effects on the proliferation,migration and invasion of NSCLC.

Background: MicroRNAs (miRNAs) exert an essential contribution to obesity and type 2 diabetes mellitus (T2DM). This study aimed to investigate the differences of miRNAs in the presence and absence of T2DM in patients with obesity, as well as before and after bariatric surgery in T2DM patients with obesity. Characterization of the common changes in both was further analyzed. Methods: We enrolled 15 patients with obesity but without T2DM and 15 patients with both obesity and T2DM. Their preoperative clinical data and serum samples were collected, as well as 1 month after bariatric surgery. The serum samples were analyzed by miRNA sequencing, and the miRNAs profiles and target genes characteristics were compared. Results: Patients with T2DM had 16 up-regulated and 32 down-regulated miRNAs compared to patients without T2DM. Improvement in metabolic metrics after bariatric surgery of T2DM patients with obesity was correlated with changes in miRNAs, as evidenced by the upregulation of 20 miRNAs and the downregulation of 30 miRNAs. Analysis of the two miRNAs profiles identified seven intersecting miRNAs that showed opposite changes. The target genes of these seven miRNAs were substantially enriched in terms or pathways associated with T2DM. Conclusion We determined the expression profiles of miRNAs in the obese population, with and without diabetes, before and after bariatric surgery. The miRNAs that intersected in the two comparisons were discovered. Both the miRNAs discovered and their target genes were closely associated with T2DM, demonstrating that they might be potential targets for the regulation of T2DM.

【Objective】 To compare the value of CT pulmonary angiography (CTPA) and echocardiography in predicting the degree pulmonary hypertension (PH). 【Methods】 Fifty-four patients in our hospital who underwent right heart catheterization, CTPA and echocardiography for suspected or confirmed PH from November 2013 to April 2021 were retrospectively recruited. Pulmonary artery systolic pressure (PASP) and mean pulmonary artery pressure (PAMP) were measured by right heart catheterization. According to PAMP, the patients were divided into non-PH group and mild, moderate, and severe PH groups. The three-dimensional model of the pulmonary artery was obtained by computer-aided segmentation, and the best fitting circle diameter (Dfit), inscribed circle diameter (Dmin), circumscribed circle diameter (Dmax), hydraulic diameter (Dh), cross-sectional area (Area), circumference (Scf), and the largest area and largest short diameter of the right ventricle were measured. Echocardiography was used to estimate PASP. The differences in the above parameters between different PH groups were compared, the correlations of the above parameters with PASP and PAMP were analyzed, and statistically significant indicators were included to establish three predictive models of PAMP (Model 1: CTPA pulmonary artery; Model 2: CTPA pulmonary artery+CTPA right ventricle; Model 3: CTPA pulmonary artery+CTPA right ventricle+echocardiography), and receiver operating characteristic (ROC) curves were used to compare the diagnostic performance of the three models. 【Results】 Some parameters of main pulmonary artery (Dfit, Dmin, Dmax, Dh, Area, Scf), right pulmonary artery (Dmax, Dh, Area, Scf), left pulmonary artery (Dfit), and right ventricular short diameter increased with the increase of PAMP (P<0.05). Dfit, Dmin, Dh, and area of main pulmonary artery, right pulmonary artery and left pulmonary artery were positively correlated with PASP and PAMP (P<0.05). Right ventricular short diameter and right ventricular maximum area were positively correlated with PASP (P<0.05), and right ventricular short diameter was positively correlated with PAMP (P<0.05). The estimated value of pulmonary artery systolic blood pressure in echocardiography was positively correlated with PASP and PAMP (P<0.05). Model 1, Model 2 and Model 3 could all be used to identify mild PH and moderate PH, among which Model 3 had the best performance in identifying non-PH and mild PH, moderate PH and severe PH. 【Conclusion】 CTPA and echocardiography are helpful in assessing the degree of PH, and the combination of the two has better accuracy in distinguishing non-PH from mild PH, moderate and severe PH.

Objective:To explore the effect of continuous blood purification (CBP) on the immunity and endothelial cell function of patients with sepsis.Methods:A prospective study was conducted. The patients aged ≥18 years old and meeting the diagnostic criteria of sepsis admitted to the department of critical care medicine of Binzhou Medical University Hospital from March 2019 to October 2020 were selected as the research subjects, and the patients were divided into standard treatment group and CBP treatment group according to random number table method. Both groups were given standard treatment including initial fluid resuscitation, infection source control and antibiotics according to the 2016 international guidelines for the management of sepsis and septic shock. CBP treatment group was additionally given continuous veno-venous hemofiltration (CVVH) at a dose of 25-30 mL·kg -1·h -1 and blood flow rate of 150-200 mL/min for more than 20 hours a day for 3 days. The clinical data of patients including blood lactic acid (Lac), procalcitonin (PCT), lymphocyte count (LYM), acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment (SOFA) score were recorded before treatment and 1 day and 3 days after treatment. At the same time, the venous blood was collected, and the immune function related indexes [interleukins (IL-4, IL-7), programmed death receptor-1 (PD-1), programmed death ligand-1 (PD-L1), interferon-γ (IFN-γ)] and endothelial cell injury related markers [soluble thrombomodulin (sTM), angiopoietin-2 (Ang-2), von Willebrand factor (vWF), heparan sulfate (HS), syndecan-1 (SDC-1)] levels in serum were determined by enzyme-linked immunosorbent assay (ELISA). The length of intensive care unit (ICU) stay of patients in the two groups was recorded, and the outcomes of patients in the two groups were followed up for 28 days. Results:Finally, 20 patients were enrolled in the standard treatment group, and 19 patients were enrolled in the CBP treatment group. There were no significant differences in gender, age and infection site between the two groups. The length of ICU stay in the standard treatment group was (10±5) days, and 5 patients died and 15 patients survived after 28 days. The length of ICU stay in the CBP treatment group was (9±4) days, and 8 patients died and 11 patients survived after 28 days. There were no significant differences in the length of ICU stay and number of patients who died within 28 days between the two groups (both P > 0.05). There were no significant differences in the Lac, PCT, LYM, APACHEⅡ score, SOFA score and immune function and endothelial cell injury related indexes before treatment and 1 day after treatment between the two groups. After 3 days of treatment, the Lac, PCT, APACHEⅡ score and SOFA score of the CBP treatment group were significantly lower than those before treatment, and pro-inflammatory and anti-inflammatory cytokines such as IFN-γ and IL-4, apoptosis-related indicators such as PD-1 and IL-7, and endothelial injury related factors such as sTM, SDC-1 and HS were significantly improved compared with the pre-treatment, the improvement degree of the above indicators was more obvious than that of the standard treatment group, and LYM was significantly higher than that of the standard treatment group (×10 9/L: 1.3±0.3 vs. 0.9±0.4, P < 0.05), IL-4, IFN-γ, IFN-γ/IL-4 ratio, IL-7, PD-1, sTM, SDC-1, HS, and Ang-2 were significantly lower than those of the standard treatment group [IL-4 (ng/L): 2.8 (1.5, 3.2) vs. 3.3 (2.7, 5.2), IFN-γ (ng/L): 6.3 (5.4, 106.5) vs. 217.9 (71.4, 517.1), IFN-γ/IL-4 ratio: 3.7 (1.8, 70.3) vs. 59.1 (18.3, 124.9), IL-7 (ng/L): 4.6 (3.2, 5.1) vs. 6.3 (5.2, 8.0), PD-1 (μg/L): 0.04 (0.03, 0.06) vs. 0.08 (0.05, 0.12), sTM (μg/L): 4.9 (4.3, 7.4) vs. 8.7 (6.0, 10.8), SDC-1 (μg/L): 0.6 (0.3, 1.1) vs. 0.9 (0.8, 2.5), HS (ng/L): 434.8 (256.2, 805.0) vs. 887.9 (620.1, 957.3), Ang-2 (ng/L): 934.0 (673.3, 1 502.1) vs. 2 233.9 (1 472.5, 3 808.4)], the differences were statistically significant (all P < 0.05). Conclusion:CBP treatment can eliminate the patient's immunosuppressive state, reduce a variety of endothelial injury markers and the degradation of glycocalyx, but cannot decrease the 28-day death risk or shorten the length of ICU stay.

ObjectiveTo explore the effect of Anmeidan on the sleep quality and serum levels of brain-derived neurotrophic factor （BDNF）， glial fibrillary acidic protein （GFAP）， and irisin in the patients with chronic insomnia. MethodA multicenter， randomized， double-blind， placebo-controlled clinical study was carried out， including 480 patients with chronic insomnia （deficiency syndrome） in Wuhan （Hubei）， Guangzhou （Guangdong）， and Lanzhou （Gansu）. They were randomized into an observation group and a control group at a ratio of 1∶1. The observation group was orally administered with Anmeidan granules at a dose of 11 g， 3 times per day， and the control group with Anmeidan simulant at a dose of 11 g， 3 times per day， Both groups of patients received sleep education after enrollment. After 4 weeks of medication， the Athens insomnia scale （AIS） scores， Spiegel scale scores， and serum levels of BDNF， GFAP， and irisin were compared between the two groups as well as between before and after treatment. ResultA total of 480 adult patients with chronic insomnia were enrolled in this study， with 64 patients falled off. Finally， the 415 patients were included in the analysis， including 213 patients in the observation group and 202 patients in the control group. There was no difference in age or sex between the two groups of patients. Compared with before treatment， the treatment in both groups decreased the AIS and Spiegel scores （P<0.01）. After treatment， the observation group had lower AIS and Spiegel scores than the control group （P<0.01）. The treatment in the observation group slightly lowered the level of BDNF， elevated the level of irisin （P<0.05）， and lowered the level of GFAP （P<0.05） in the serum. After treatment， the observation group showed higher level of irisin （P<0.05） and lower levels of BDNF and GFAP in the serum than the control group. ConclusionAnmeidan may improve the sleep quality of patients with chronic insomnia by elevating the irisin level and lowering the GFAP level in the serum.
